I don't believe that faith or belief should ever be blind. That's like you closing your eyes and letting a blind man lead you across a busy intersection - you're willingly screwing yourself and letting everything come down to how strong your inner fiber is. And therein lies the problem: people's inner fiber aren't strong enough.
On one end, you have the people who view everything as "an act of God". Cat ate your pet hamster? Broke your hand in 3 places after someone pushed you? Teacher gives you an F cuz he don't like you? All these, they'll explain away as "God's will". Whatever happened to our own free will [that God gave us] is up in the air, as far as they're concerned.
The other end of the spectrum, there are the people who use the religion like crutches. Junior died? House got foreclosed? Hell, won a $96049604569 lottery jackpot? All they do is say "God help me as I go through this [insert situation here]." These guys didn't receive the memo that God helps those who help themselves.
I'm not saying every christian is like that, but I've seen a lot of them, regardless of denomination [that the right term???]. Like I said, some people, they don't have inner fiber strong enough to handle believing in something, worse yet if it's blind belief.
No, IMHO, a person should only believe in what he thinks is right, and not some doctrine that some wheezing old guy laid down. It's true, belief is the strongest thing man has, bar none. And that's exactly why we shouldn't just surrender our beliefs like that. I hope you got my point.
PS
Again, nothing against hardcore religious types out there. Just stating my take on it. Chill!
